Trematoda
Sign in to saveAlso known as Fluke, Trematode
Trematoda is a class of flatworms known as trematodes, and commonly as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is a mollusk, usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five vertebrate groups: mammals, birds, amphibians, reptiles, and fish.
OverviewAI-generated
Trematoda is a class within the phylum Platyhelminthes of the kingdom Animalia. Commonly referred to as flukes, this taxon is accepted in the World Register of Marine Species. Organisms in this class inhabit marine, brackish, and freshwater environments.
The classification has generated significant scientific attention, with 37,669 records in PubMed and 220,795 occurrences in GBIF. Additional data is held by institutions including MSB, YPM, USNM, NMU, and DMNS, with records from the United States and Canada. The subject is also referenced by 1,253 other encyclopedia articles.

Les trématodes (Trematoda) forment une classe au sein du phylum des plathelminthes. Tous les trématodes sont des vers parasites. Les classifications précédentes les scindaient en deux ordres (ou deux sous-classes), les Monogenea et les Digenea, selon que leur cycle de vie impliquait un ou deux hôtes intermédiaires (Monoxène ou hétéroxene). Cependant la taxonomie des plathelminthes est en train de subir une importante révision. Les sources modernes classent les Monogenea en tant que classe séparée au sein du phylum. Il existe deux groupes importants en pathologie humaine : Les douves hermaphrodites (ex : Clonorchose et douve du foie) Les schistosomes (ou bilharzies) dont les sexes sont séparés.

Ces œufs donnent naissance à des larves miracidium qui possèdent un revêtement ciliée le

Trematoda is a class of flatworms known as trematodes, and commonly as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts.

==Etymology== Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. The etymology of trematode stems from the Greek word trēmatṓdēs, which means "pierced with holes", and refers to the worm's sucker, which pierces a hole in the host while the worm is attached and feeding.
